George Doyle/Stockbyte(PORT SAINT LUCIE, Fla.) -- A school bus aide in Port Saint Lucie, Fla. was arrested and charged with stalking after surveillance footage showed her allegedly bullying a 5-year-old boy.

Newly released surveillance videos show Daneta McPherson, 37, yelling at the boy and threatening to take him home with her.

In the video, McPherson is seen towering over the child, reducing him to tears as she berates him on the bus.

On at least one occasion, McPherson grabbed the boy and caused him to hit his head on the side of the bus, according to the police report.

A school employee first reported the alleged abuse to police and provided them with videos in December. After a four month long investigation, McPherson was arrested on Thursday.
